Two pneumatic valve plate flange _ pneumatic components factory valve industry

Pneumatic pneumatic valve plate flange two pneumatic valve overview: 2 plate flange pneumatic valve, pneumatic valve is a kind of floating floating design BS5351 and API 6 d standard, adopts the design of full size or reducing diameter for 1/2 'mm to 10 mm,' class of 150 and 300 pounds, working temperature according to the valve material can meet the design, low temperature and room temperature by using ANSI B16 connection length of the valve. 10 and the flange in accordance with ANSI B16. 5 design; Two type pneumatic valve flange used the fire protection and anti-static design, this valve is widely used in electric power, petrochemical, pharmaceutical and food industries. Two plate flange structure design of pneumatic valve: two plate flange pneumatic valve is the valve body along the tunnel axis is vertical section can be divided into asymmetrical about two and a half, aerodynamic body from cutting face load, about two and a half body with a pneumatic valve flange connection or threaded connection; Because the body is divided into two and a half, compared with the monolithic, half body piece weight is lighter, casting or forging and machining. 2 plate flange of the pneumatic valve floating design: two pneumatic valve adopts the design of floating plate flange, because of lack of support shaft, the aerodynamic body aerodynamic body by two seat holding a floating state, it is mainly used for cutting on pipeline, distribution, and change the flow direction of medium. It is the structure of the body with two seat sealing, a pneumatic clamping between them, the aerodynamic body by body is free to rotate in the seat sealing; When open, pneumatic hole and pipe diameter, zui has ensure the working medium resistance is small. When the valve rod rotation 1/4 turn, pneumatic hole vertical to the channels of the valve, depend on two seat sealing of pre-tightening force and medium pressure to the pneumatic body tightly pressed on the outlet seat sealing, to ensure that the valve seal completely. Two type flange pneumatic valve features: (1) full size or reducing. (2) the fly out of the valve stem. (3) antistatic device. (4) low leakage prevention design packing and stuffing box. (5) optional locking devices: pneumatic lock slag pneumatic valve forged steel flange pneumatic valve technical features Q611F pneumatic three type pneumatic valve Q911F/H/H electric three type pneumatic valve
